Abstract

This project presents a solar power generation system with a power smoothing function achieved through the control of the DC-link voltage, implementation of a current controller, and utilization of a Phase-Locked Loop (PLL) for frequency control. The system aims to mitigate power fluctuations caused by variations in solar irradiance and other factors, ensuring a stable and constant power supply.The proposed SPGS consists of a solar cell array, a battery set, a dual-input buck-boost DC-AC inverter (DIBBDAI) and a boost power converter (BPC).The DIBBDAI combines the functions of voltage boost, voltage buck and DC-AC power conversion. The BPC acts as a battery charger between the solar cell array and the battery set. For the proposed SPGS, the DC power that is provided by the solar cell array or the battery set is converted into AC power through only one power stage. The solar cell array also charges the battery set through only one power stage. This increases the power conversion efficiency for the solar cell array, the battery set and the utility. The battery set is charged/discharged when the output power of the solar cell array changes drastically, in order to smooth the output power from the SPGS. The DC-link voltage control is responsible for regulating the voltage level within the system, ensuring it remains within a specified range for optimal operation. This control is achieved using a DC-DC converter, which adjusts the voltage level based on system requirements and solar panel output. The current controller plays a crucial role in regulating the current flow from the solar panels to the DC-link. By operating at the maximum power point (MPP), the current controller optimizes power generation. The PLL frequency control ensures synchronization between the generated power and the utility grid. By monitoring the grid frequency and adjusting the frequency of the generated power accordingly, the system seamlessly integrates with the grid and facilitates efficient power transfer.
